Higher efficiency solar cells are needed to reduce mass, volume, and cost of DoD space missions. However, to achieve higher efficiency and radiation hardness of the best to date multi-junction photovoltaic (PV) devices, several challenges must be addressed. This project aims to develop: 1) Quantum Well (QW)-based multi-junction cell that exhibits enhanced efficiency, and 2) Radiation-hardened PV c ...

Hypersonic missile defense systems are being designed to reach global threats. During flight, external surfaces are predicted to reach temperatures in excess of 2200C. As a result, innovative, high performance thermal protection systems (TPS) are of great demand. Among ultra-high temperature ceramics (UHTC), it is well known that ZrB2- and HfB2-based materials have high melting temperatures and ...

The Missile Defense Agency (MDA) seeks technical investigations related to the development and application of advanced electronic materials, processes, and devices to meet its need for radiation hardened, high performance electronics for critical space and missile applications. With the advent of smaller transistor dimensions and reductions in price per bit, significant changes in materials and pr ...

Gallium Nitride (GaN) substrates are ideal materials for fabrication of high-power and high-frequency devices based on III-V materials. The current state-of-the-art Chemical Mechanical Polishing (CMP) methods are plagued by several challenges, including, surface charge affects due to surface contamination, and sub-surface damages, which can limit the quality of III-V devices. Furthermore, there is ...

This Phase I STTR program seeks a new fabrication method to produce stronger (>100 kpsi) and tougher (>10 MPa m1/2) ultra high temperature Ta-Hf-C-based composites (UHTC) with an outstanding oxidation resistance for use as thermal protection systems for hypersonic applications, as well as for advanced rocket nozzle throat components. UES will apply a novel "Top Down" approach to control the micro ...

The primary objective of the proposed research is to develop proof of concept of a software programmable X-Band radar system using low cost antenna array technology with digital beamforming architecture based on multiple receiver channels. The performance objectives will aim at a minimum of 400 MHz instantaneous bandwidth and a minimum instantaneous dynamic range of 52 dB. The objective of the t ...

We propose to develop a computational model of leadership designed to capture complex variables including cultural differences in leadership requirements along with task differences, primarily ill-defined goals, which pose leadership challenges. Rather than avoiding these kinds of complexity and developing a computational model that is unlikely to scale up, we believe there is more to be gained b ...

Users of OneSAF are offered the potential to specify entity behaviors using a flowchart-based composer. However, that tool lacks utility because it is schematic instead of graphical, and does not foster intuitive understanding of temporal relationships. The goal of the proposed project is to simplify the behavior composing process, supplementing the composer architecture with a graphical interfa ...

The goal of this program is to develop high-speed interceptor communications solutions that are hardened to space and nuclear radiation, including high altitude nuclear explosions (HANEs). As part of this program, AET will specifically investigate the use of advanced diamond technology for communications applications. The approach of AET, Inc. is to first identify a communication system architectu ...

Develop software visualization modeling tool to assist in the design and fabrication of cold atom chips. Tool will calculate the magnetic field from a specification of conductor geometry and currents flowing through them.
